I currently work for a small OPE sales/service shop. We sharpen mower blades and chainsaw chains--about 700 blades/year. I'm thinking of starting my own sharpening business on the side. I'd sub the shop's blades and chains, plus advertise and run a pickup/delivery service to local hardware stores, etc. I'd also sharpen hedgetrimmer blades, then maybe add other sharpening services in the future. Has anyone tried this? Any advice--equipment, advertising, getting more customers, etc.? Thanks!
